CAR-WHEEL BEARING.

SPECIFICATION forming partof Letters Patent No. 585,523, dated June 29,189,7'. Application led November 9, 1896. Serial No. 611,517. (Nomodel.)

To @ZZ whom it may concern..-

Be it known that I, JOHN T. JONES, a citizen of the United States,residing at Iron Mountain, in the county of Dickinson and State ofMichigan, have invented certain new and useful Improvements in Oar-WheelBearings; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in car-wheels; and it consists ofcertain novel features hereinafter described and claimed.

Reference is had to the accompanying drawings, wherein the same partsare indicated by the same letters throughout both views.

Figure l represents a side elevation of a v car-wheel constructedaccording to my invention, partly in section, on the line l l of Fig. 2;and Fig. 2 is a section through the same, taken on the line 2 2 of Fig.l.

The wheel is composed of two separate portions-viz., the outer portionor wheel proper, A, which is composed of the web A and the tread-ringA2, having the usual flange A3, and the hub B, having the centralopening B0 for the axle D, as shown.

The web A has a circular central opening and around this opening athickened portion A4. A groove a0 is formed centrally around theinterior of this opening in the web, and the beveled sides d 0L of thisopening diverge outward from the said groove, as seen in Fig. 2. Thesmallest diameter of this central opening in the web is slightly greaterthan the largest diameter of the hub B, as also seen in Fig. 2 of thedrawings.

The hub B has a groove bo, formed centrally around its periphery, andhas beveled surfaces b b,diverging outward from said grooves.

The antifriction-balls C run in the grooves a0 and bo in the centralopening of the web A and in the periphery of the hub B, respectively.These balls are put into position through a radial opening e0 in the hubB, and into this radial opening is afterward iitted a plug E, which isheld in position by means of Aa pin or key c, driven through an openingin the hub and an opening through the said plug, as seen most clearly inFig. 2. The ends of the place of the inner cotter-pin d, if preferred. 4

The outer portion or wheel proper, A, may rotate upon the balls C aroundthe hub B, and the latter, as above described, may also rotate upon theaxle D. The outer portion A will be held upon the hub B by means of theballs O, which together act as a continuous key to hold the partstogether, but at the same time permit of a slight play or swaying motionof the outer portion A of the wheel. One of the advantages of myconstruction is that this lateral play will allow the outer portion ofthe wheel to overcome any unevenness in the track laterally withoutbinding at the hubs, as in going around curves. It will also be seenthat the balls may be readily cleaned by means of a brush or othersuitable implement, when necessary, without removing them from thewheel. These and many other advantages of my herein described wheel willbe apparent to any one skilled in the art.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

l. In appear-wheel, the combination with the circular hub B havingcentral opening Bo for the axle, and having a shallow groove 130 aroundits periphery, and the radial opening e0 leading from said centralopening to said peripheral groove; a removable plug provided withconcaved ends adapted to close said radial opening, and means forholding said plug in position; of the wheel proper A composed of atread-ring A2, and a web having a central circular opening therein of aslightly greater diameter than the periphery of said hub, with a centralgroove do around the circumference of said opening; and balls worky ingbetween said hub and web in said grooves a0 and 19, and serving both asa bearing between the wheel and its hub and to hold the said partstogether, substantially as described.

2. In a car-wheel, the combination with the IOO circular hub B havingcentral opening B0 for the axle, and having a shallow groove bo aroundits periphery, and the radial opening @.0 leading from said centralopening to said peripheral groove; a removable plug provided withconcaved ends adapted to close said radial opening, and means forholding sai d plug in position; of the Wheel proper A composed of awidened tread-wing A2, and a thin web A having a circular centralopening therein of a slightly greater diaineterthan the peripl1- ery ofsaid hub, With a thickened annular portion 'around said opening, and acentral groove a0 around the circumference of said opening; and ballsWorking between said hub 15 and web in said grooves a0 and bo, andserving both as a bearing between the Wheel and its hub and to hold thesaid parts together, substantially as described.

In testimony whereof I affix my signature 2o in presence of twoWitnesses.

JOHN T. JONES.
